Linear OOA(2²⁵⁸, 142, F₂, 4, 61) (dual of [(142, 4), 310, 62]-NRT-code), using OOA 2-folding based on linear OOA(2²⁵⁸, 284, F₂, 2, 61) (dual of [(284, 2), 310, 62]-NRT-code), using

discarding factors / shortening the dual code based on linear OOA(2²⁵⁸, 285, F₂, 2, 61) (dual of [(285, 2), 312, 62]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(16³⁶, 57, F₁₆, 2, 30) (dual of [(57, 2), 78, 31]-NRT-code), using
    - discarding factors / shortening the dual code based on linear OOA(16³⁶, 64, F₁₆, 2, 30) (dual of [(64, 2), 92, 31]-NRT-code), using
      - algebraic-geometric NRT-code AG(2;F,97P) [i] based on function field F/F₁₆ with g(F) = 6 and N(F) ≥ 65, using
        the Hermitian function field over F₁₆ [i]
  2. linear OA(2¹, 5, F₂, 1) (dual of [5, 4, 2]-code), using
    - discarding factors / shortening the dual code based on linear OA(2¹, s, F₂, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
      - parity-check code [i]
